Chandler's back is acting up and he's been out the last few games, which really hurts their interior D. Dallas has to face some decent teams (PHO/NO/LAC/Hou) while OKC still has games against LAL/DEN/SAC/MIL. A one game lead can be erased.

Personally, I'd like to see the Mavs hold onto their lead and see a Mavs-Lakers matchup. Somehow, there hasn't been a single playoff between these two in the Dirk-Kobe era.
